Title: Engine providing complete circular motion
Inventor: KOSHIHATA SEIJI
IPC: F02B53/00
Filed: 1982-04-21
Abstract: PURPOSE:To increase an engine output power, by constituting an engine providing a complete circular motion such that rotors are provided inside cylinders wherein a large diameter circle and a small diameter circle are crossing with each other. CONSTITUTION:A large rotor 4 and a small rotor 5 are caused to rotate at a speed ratio of 1:2 with their contact surfaces kept as air-tight. A fuel oil which is sucked into a suction port 11 provided at a side of small cylinder 2 undergoes a compression stroke as the small rotor 5 starts rotating, and is fed into a semi-circular portion 7 of the large rotor 4 during a compression stroke. As the small rotor 5 continues to rotate, the fuel oil is further compressed by the small rotor 5 and the large rotor 4 and exploded upon the small rotor 5 having its pawls 8 and 9 being fully received in the semi-circular portion 7 of the large rotor 4. In this manner, complete circular motions of the large rotor and the small rotor ensure a complete transmission of torque to a shaft and thus provide to an engine an efficiently high output power.

Title: Computer system
Inventor: KOMASAKA TOSHIO
IPC: G06F12/00
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce the time required for maintenance work by permitting a computer system itself to self-diagnose an operation environment and restoring an abnormal part based on the judgment of the computer system itself when abnormality occurs in the result of diagnosis. SOLUTION: The presence of absence of the change of the system environment of the computer system 2, namely, the file of software and firmware is diagnosed by comparing system information which a system information file 23 holds with a system file 21. When it is judged that the file of firm ware changes as the compared result between system information which the system information file 23 holds and the content of the system file 21, firmware is self-restored in accordance with the content of a backup file 25. Thus, the efficiency of maintenance is not affected by the size of the system and the ability of a user. Time required for maintenance is reduced and the waiting time of the user is shortened.

Title: Compression ignition internal combustion engine
Inventor: MURATA HIROKI
IPC: B60L50/16
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce generation amount of soot. SOLUTION: A first combustion and a second combustion can be selectively switched. In the first combustion, soot is hardly generated because the amount of recirculated exhaust gas supplied into the combustion chamber 5 is larger than that of the recirculated exhaust gas obtained when generation amount of soot becomes peak. In the second combustion, the amount of recirculated exhaust gas supplied into the combustion chamber 5 is smaller than that of the recirculated exhaust gas obtained when generation amount of soot becomes peak. When switching combustion from the first to the second or vice versa, the fuel injection amount is reduced. The reduction in the output torque of the engine can be compensated by the output torque of the electric motor 32.

Title: Motor driven telescopic antenna
Inventor: SHINKAWA MASAMI
IPC: H01Q1/10
Filed: 1979-05-30
Abstract: PURPOSE:To make unnecessary a clutch and a limit switch, by interrupting power between the brushes of a motor through the axial movement of a rotary shaft, when an antenna element is finished for the operation of extension and contraction and the wheel stops rotation. CONSTITUTION:When switches S1, S2 of a power supply circuit are connected to the position of S1U, S2U, a closed loop is formed among power supply E, brush B1, commutator 7, armature 5, brush B3 and power supply E, and a main body 1 turns forward. Thus, the torque of the main body 1 is delivered to a wheel 21 via a worm 11 and a wire driving wheel 22 turns toward the arrow. Then, when a driving wire is introduced and an antenna element A reaches a limit of extension or contraction, the wheel 21 is disable for rotation. Thus, when a rotary shaft 6 moves downward and an insulating ring 8 of the commutator 7 moves to the position of the brush B1, the conduction between the brush 1 and the commutator 7 is interrupted and the main body 1 stops for the rotation. Next, when the switches S1, S2 are switched to the contacts S1D and S2D, the element A goes downward and the main body 1 is stopped at the limit.

Title: Convergence correcting device for color picture tube
Inventor: TOSHIYASU MASAYUKI
IPC: H01J29/54
Filed: 1981-04-30
Abstract: PURPOSE:To realize the correction of a vertical-line lateral-direction mis-convergence or the prevention of the deterioration of the said mis-convergence, which is not resolved by a deflection york itself, by using a ferromagnetic substance or a non-magnetic substance as the material of a clamping band according to the direction of the said mis-convergence. CONSTITUTION:When a vertical-line lateral-direction mis-convergence YH realized by a pin-cushion-free-type deflection york 1 is an under convergence, a  clamping band 7 used for clamping a C.P-ASSY5 should be prepared from a ferromagnetic substance such as iron so as to reduce the pulse component of a  magnetic field leaking out from the back of the york 1 and to resolve the under  convergence YH. In contrast, the clamping band 7 should be prepared from a  non-magnetic substance in correcting a state of an over convergence. The  amount of the above correction becomes the smallest when the band 7 is located in the back of a cathode 6, and becomes larger as the band 7 is located closer  to the side (A) of a screen.

Title: Occupancy releasing system for data base
Inventor: MITANI MASAAKI
IPC: G06F12/00
Filed: 1987-03-20
Abstract: PURPOSE:To improve the simultaneous execution of other application programs by adding a means removing a specified record at an optional point of time and releasing occupancy at the time of accessing a data base. CONSTITUTION:The occupancy of a record a1 updated after the retrieval of a record is permanently fixed so that the occupancy of the record a1 is not released up to the end of transaction. After retrieving a record b1 the occupancy is released and EXCEPT CURRENT is specified to temporarily fix the latest record b1. Consequently, the record a1 is permanently fixed and the record b1 is temporarily fixed, so that the occupancy of any record is not released. Since the occupancy is released by specifying EXCEPT CURRENT after the retrieval of a record b2, the record b2 is temporarily fixed. Since the record a1 is permanently fixed, the occupancy of the record b1 is released.
